 Renewable energy for transportation

2.      Definition of renewable energy

Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished. For example, sunlight or wind keep shining and blowing, even if their availability depends on time and weather.

While renewable energy is often thought of as a new technology, harnessing nature’s power has long been used for heating, transportation, lighting, and more. Wind has powered boats to sail the seas and windmills to grind grain. The sun has provided warmth during the day and helped kindle fires to last into the evening. But over the past 500 years or so, humans increasingly turned to cheaper, dirtier energy sources such as coal and fracked gas.

3.      Types of renewable energy for transportation  

a.      Gasohol

gasohol, a gasoline extender made from a mixture of gasoline (90%) and ethanol (10%; often obtained by fermenting agricultural crops or crop wastes) or gasoline (97%) and methanol, or wood alcohol (3%). Gasohol has higher octane, or antiknock, properties than gasoline and burns more slowly, coolly, and completely, resulting in reduced emissions of some pollutants, but it also vaporizes more readily, potentially aggravating ozone pollution in warm weather. Ethanol-based gasohol in which the ethanol is made from corn is expensive and energy intensive to produce, and can damage rubber seals and diaphragms and certain finishes if the ethanol is present in higher concentrations. Since 1998, however, many American automobiles have been equipped to enable them to run on E85, a mixture of 85% ethanol and 15% gasoline. Methanol-based gasohol is also expensive to produce and is toxic and corrosive, and its emissions produce cancer-causing formaldehyde.

b.      Biodiesel

Biodiesel is an alternative fuel similar to conventional or ‘fossil’ diesel. Biodiesel can be produced from straight vegetable oil, animal oil/fats, tallow and waste cooking oil. The process used to convert these oils to Biodiesel is called transesterification. Biodiesel has many environmentally beneficial properties. The main benefit of biodiesel is that it can be described as ‘carbon neutral’. This means that the fuel produces no net output of carbon in the form of carbon dioxide (CO2). This effect occurs because when the oil crop grows it absorbs the same amount of CO2 as is released when the fuel is combusted. I

c.       Natural gas

Natural gas is a fossil energy source that formed deep beneath the earth's surface. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4). In some places, natural gas moved into large cracks and spaces between layers of overlying rock. The natural gas found in these types of formations is sometimes called conventional natural gas. Natural gas withdrawn from natural gas or crude oil wells is called wet natural gas because, along with methane, it usually contains NGL—ethane, propane, butanes, and pentanes—and water vapor.

d.      Hydrogen energy

Hydrogen fuel is a zero-emission fuel when burned with oxygen. It can be used in electrochemical cells or internal combustion engines to power vehicles or electric devices. It has begun to be used in commercial fuel cell vehicles such as passenger cars, and has been used in fuel cell buses for many years. It is also used as a fuel for the propulsion of spacecraft. Hydrogen is usually considered an energy carrier, like electricity, as it must be produced from a primary energy source such as solar energy, biomass, electricity (e.g. in the form of solar PV or via wind turbines), or hydrocarbons such as natural gas or coal.Conventional hydrogen production using natural gas induces significant environmental impacts; as with the use of any hydrocarbon, carbon dioxide is emitted.

e.       Hybrid engine

Hybrid engines combine two different sources of power to move the vehicle. The first source is the traditional internal combustion engine, which produces power by burning fuel, usually gasoline. The second source is usually an electric motor that gets its power from a battery pack within the vehicle. The engine and the electric motor work together to produce the power the vehicle needs to operate. However, the internal combustion engine in a hybrid car is typically much smaller than usual for efficiency and to accommodate the electric motor.One way to boost hybrid power is to update the batteries. For instance, the battery pack used in the third-generation Toyota Prius is smaller and more efficientthan those in previous versions of the car, which gives it a slightly higher power output
